Embodiment Construction

[0029] figure 1 A preferred embodiment of the inventive plug-type coupling is shown, wherein here only the coupling element 20 is shown in a perspective view. The coupling element is a one-piece plastic part which is produced by injection moulding. Correspondingly, the injection mold is filled with plastic which defines the features of the coupling element 20 described in detail below. After injection molding and cooling of the coupling element 20, the coupling element 20 is demolded.

[0030] Preferably, the plastic of the coupling element 20 has a Shore A hardness in the cold state in the range of 20 to 120, preferably 20 to 90 Shore A hardness. In the preferred fiber-reinforced plastics, the nature of the fiber material (filler) and the shape, size and distribution of the fibers influence the mechanical properties of the material.

[0031] Further preferably, the one-piece coupling element 20 is made of a thermoplastic elastomer such as polyamide (PA), polypropylene (PP)...

Abstract

The present disclosure is directed to a coupling element 20 for the releasable connection of a first component B1 to a second component B2. The coupling element has an annular basic element 22 comprising a fastening structure 30 at a radially outer side. Further, the basic element comprises a socket-like holding structure 40 at a radially inner side. The socket-like holding structure comprises a centrally arranged supporting element 42 as well as a plurality of holding webs 44, 46. The holding webs 44, 46 comprise at least a first 44 and a second 46 web section. The first web section 44 encloses with an axis of symmetry S of the coupling element 20 an angle alpha from a range of 45 DEG<=alpha<=90 DEG and the first web section 44 and the second web section 46 are arranged in an obtuse angle with respect to each other.

Description

technical field [0001] The invention relates to a plug-type coupling for a releasable or detachable connection of a first part to a second part, wherein the plug-type coupling consists of a coupling element and a ball stud. Background technique [0002] In the prior art, various plug-type couplings are known for the connection of two components. Depending on the configuration of the plug-type coupling, most of which cooperate with ball studs or ball studs, and the choice of material, different connection properties are achieved. The terms "ball stud" and "ball stud" are used synonymously. They indicate elongated pin-like members with spherical ends. [0003] DE 299 20 379 U1 and EP 0 902 198 B1 describe plug-type couplings which, due to their construction and the elastic material from which they are made, are able to damp vibrations of the components. This is achieved in particular by the certain movability of the ball head after it has been snapped into the coupling and ...
